This week the Grand Tour tent is on the shores of Loch Ness in Scotland, from where Jeremy Clarkson, Richard Hammond and James May introduce their experiences of buying used Maseratis with their own money and then using them to tour the drizzle flecked landscapes of the North of France. Along the way, they encounter worrying noises, unusual electronics, a small engine fire, and the cruel delight of watching James trying to drive with a broken arm. Also in this programme, Richard is at the Eboladrome track trying out the Abarth 124 Spider as he discovers if it's a real Italian sports car or just a Mazda in a fancy suit. Plus, gold medal winning Olympic cyclist turned car racer Sir Chris Hoy arrives to try Celebrity Brain Crash and Jeremy has an innovative way to install cutting edge features in an older car.
